With SoftRAID 5.6.4 'SoftRAID for ThunderBay' has been renamed 'SoftRAID XT', and 'SoftRAID Lite for ThunderBay' is now 'SoftRAID Lite XT'. (SoftRAID XT is a version of SoftRAID bundled with OWC hardware).

SoftRAID now reports the number of total bytes written for most SSDs. If available, this is displayed in the disk tile for the SSD (in SoftRAID's main UI window).
We will be adding support for additional SSDs in the future.
If the total bytes written value does not appear for your brand of SSD, please contact support@softraid.com so we can add it.

SoftRAID 5.6.4 contains a work-around for a macOS bug which caused a kernel panic every time Apple's Disk Utility program was used to erase a SoftRAID disk.
This bug was introduced in Mac OS 10.12. With this work-around, the Mac no longer kernel panics but the Disk Utility application still hangs.

SoftRAID takes security very seriously, and all SoftRAID DMG files are now code signed, so users can be certain the image they download from our site is an unaltered DMG file.

Details of other bug fixes in SoftRAID 5.6.4 can be found in the release notes.
